Pt-Coated Lipid Nanotubes for Glucose Oxidation in a Neutral Medium

“…Enzymatic GFCs, using natural enzymes to catalyze glucose oxidation and oxygen reduction, are biocompatible and have excellent selectivity. , However, because of the poor stability of enzymes, storage difficulty, and manufacturing cost of enzymatic GFCs, − nonenzymatic GFCs based on nanostructured noble metal catalysts (e.g., Pt, , Pd, , and Au , ) working in physiological solutions are preferred. Currently, most of the reported nonenzymatic GFCs operate in an alkaline medium. , Only a few researchers have demonstrated nonenzymatic GFCs operating in a neutral solution.…”

“…As LNTs are composed of phospholipids, which are building materials for intercellular membranes, LNTs could serve as biocompatible catalyst support. In fact, solid lipid nanoparticles, liposomes, and LNTs have been used for targeted drug delivery with minimal toxic effects. − In our previous work, it was shown that Pd nanoparticle-loaded LNTs and Au nanoparticle-modified lipid bilayers were used for glucose oxidation and direct sensing of H 2 O 2 , demonstrating the chemical and physical stability of LNT support. Pd and Au-loaded LNTs exhibited excellent catalytic activity toward glucose oxidation in an alkaline medium, but they showed minimal catalytic activity in a neutral medium.…”
